Optics set up for AR-15

[Hoser]

It is a little heavier than a 16 inch barrel, but still comes in a 41 ounces. Is this really a poor choice? I can still change!

I think the SPR contour is a little heavy for 3-gun. The 18 inch length is fine. I like an A2 or even an A1 contour under the handguards. JP sells them all ready to go.

Hoser,

I contacted JP Rifles. Unfortunately they are not selling any major components at this time as they are saving them for their own complete rifles.:banghead: Also this is a left hand build.

Do you think I should try and have the barrel fluted?

What are your thoughts on amount of necessary magnification? Again matches I have in my area do not seem to exceed 300 hundred yards and most were much closer.

I am still struggling with an optics choice. I have looked at ACOG's, Eotechs, Aimpoints, Trijicon Accupoint, etc, etc. Is variable power a waste of time? Current thought is Eotech with co-witnessed BUIS, but this is no magnification????? I just feel like I need something for more distant targets.

Figure I could always get a magnifier down the road. Again, I want to started in limited division NOT open.

Thanks for all the help and patience everyone!!!!!!

optics

this is a hard choice. I am in the market am have no clue at this point.

I'm looking at my options also and ran across this on another site regarding the Millett Zoom Dot. Thought it might add to the discussion.

I got this list of reasons the Zoom Dot is better than the Aimpoint from opticstalk.com. I haven't had a chance to research all of the items in this list, but thought I would post it for you to check out.

1. ZD has no wires to break, AP has small wires that break under use.

2. ZD has No glued LED, AP has a LED that is glued in. can come lose

3. ZD has no inter tube to reduce your vision, come lose or lose zero

4. ZD is tested to 2000+ g, it will hold up after being run over by a truck.

5. ZD can go to 300 under water for extended time and not leak, the lenses are made like a rolex watch more pressure the tighter they get.

6. ZR has no rheostat to adjust the brighness, it does it automatically to match the light conditions. If you go from bright to dim it will adjust to match the light. Note the smooth lines and no knobs sticking out of the sides of the unit.

7. the ZD will hold zero, due to the design it cant change zero due to impact less than destruction.

8. ZD will work from the range of the battery, -40 to 150+ f

9. ZD is manufactured in Huntington Beach CA. by an American company. AP is not.

10. There is no perceived parallax in the ZD, AP has visible parallax.

11. ZD can be repaired in the field if electronics ever fails, less than a min. you can replace the electronics, AP got to send it back.

12, If you want the latest in design ZD, if you want 25 yr old tec AP.

Give me A2 sights on an AR15 any day.

 

[Zak Smith]

A2 sights are great until you need to shoot fast on the move, the target contrast is low, there is low light, you need to shoot from a poor position, or weak-handed, or the target is smaller than your front sight, or your windage knob gets bumped off zero, or you can't ID or make out the target because it's too far away. Optics are a force-multiplier for rifles.

Down and dirty, within 25 yds, on open targets- I think that irons are just as fast as optics. But head shots at 40 yds or engaging 8" plates at 300 yds with A2 sights isn't easy for most- Bennie Cooley notwithstanding. I'll stick to optics.

The great thing is that theories are easy to test. Set up the course and fire up your shot timer...

 

[VegasOPM]

he great thing is that theories are easy to test. Set up the course and fire up your shot timer...

Yeah Zak- I've done that. It is pretty much a wash with close up, open targets. But inside of 25 yds, I'm pretty much relying on index and just using any sight for verification. When the targets get smaller, optics are much faster- like 4-5 seconds on a 20 second COF.

 

[taliv]

so... you're not really saying irons are as fast as red dots up close... you're saying you're point shooting and not using either sight up close

if you actually took a sight picture before pressing the trigger, at any range, wouldn't you agree a red dot is faster?

I just mounted my EoTech 3x Magnifier with my Eotech 512 (and YHM BUIS).

Haven't played with it at the range yet, but the 3x is nice and clear. It's nice to flip it to the side when you just want the "normal" hologram for CQB.

I use a 2 moa Aimpoint with a 16" pencil barrel and bulk PMC FMJBT out to 300 yds. It shot 200 yds on 12" steel fine last year, offhand. It was DRILLING them prone/kneeling. The rifle holds about 2 moa out to 200 yds, maybe more with that ammo. It would work fine on silhouettes to 300 yds, maybe more. Practice is much more important than price of equipment.

Afterthoughts: Aimpoint batteries last 7 years, on the middle setting. They don't require you to change magnification during a match. And, MANY have been carried overseas in combat zones (personal experience: they are MUCH more reliable than EOTechs). No war intended, just MO.
